[SOLVED] Arch hangs on shutdown. Kernel log messages.OK with linux-lts

I previously updated with pacman on 1st Septempter.  After another update today, my Asus Vivo E210MA laptop hangs on shutdown, and must be manually powered off.

On boot, after displaying the usual (verbose) messages, a lot of extra messages appear, immediately before the login prompt.
They are displayed in the log, when I run:
$ journalctl -k (PASTEBIN)

I can't see anything related in:
$ cat /var/log/pacman.log | grep 2023-09-2 (PASTEBIN)

The issue only affects the linux kernel.  When I boot with linux-lts, everything is normal.

I'm not sure how to troubleshoot further.
Can anyone help? :-)

The boot in the journal you posted is only 30 seconds and doesn't cover any shutdown.
But:

Aha!  That's it!  :-D

I tried to do that a while ago, but got the module name wrong.  Oops!

Thanks for your help :-)

Did you consider removing or fixing the package that provides 8821ce possibly https://aur.archlinux.org/packages/rtl8821ce-dkms-git rather than leaving it installed and providing no functionality as you have the module blacklisted?
